A metric whitelist file can be used to track the set of metrics in AMS. All other metrics will be discarded.
STEPS
- Download metric whitelist file Metric whitelist file is present in /etc/ambari-metrics-collector/conf. If not present in older Ambari versions, it can be downloaded from https://github.com/apache/ambari/blob/trunk/ambari-metrics/ambari-metrics-timelineservice/conf/unix/metrics_whitelist to the collector host.
- Adding config ams-site : timeline.metrics.whitelist.file = <path_to_whitelist_file>
- Restart AMS collector
- Verify whitelisting config was used. In ambari-metrics-collector log file, verify the line 'Whitelisting # metrics'.
